Hi,
I am looking to replace my radiator in my 1959 with a 352 Engine.

I am trying to determine if I should get a 3 row or 4 row radiator and there are a couple of different models of each(Heavy Duty, High Efficiency & Optima).

I am a little worried about clearance with the fan but I want it to have better cooling than what came with the car.

Thanks for the help.
